10 Best Smart Toilet 2026 in the United States

The KOHLER NUMI 2.0 Comfort Height Smart Toilet is designed to offer a high level of comfort and advanced functionality. One of its standout features is the bidet functionality, which includes an adjustable stainless steel wand with options for water pressure, temperature, and spray shape. The heated seat and hands-free automatic lid and flush add to the convenience, ensuring a more hygienic and comfortable user experience. The deodorizer and self-cleaning functions, using UV light and electrolyzed water, help maintain cleanliness and freshness.

The motion-activated opening and closing of the lid, along with a quiet-close feature, prevent slamming and enhance ease of use. The dual flush system offers eco-friendly water usage options, with 0.8 or 1.0 gallons per flush, contributing to energy efficiency. The added height of the seat makes it more accessible for many adults, making sitting down and standing up easier. The compact, streamlined design ensures it fits well in various bathroom settings, and the elongated bowl provides extra comfort.

However, the requirement for professional installation may be a drawback for some users, as it adds to the overall cost and effort needed to set up the toilet. Additionally, being a high-end smart toilet, the price point might be steep for budget-conscious buyers. The KOHLER NUMI 2.0 is well-equipped with features that make it a strong contender in the smart toilet market, suitable for those looking for luxury and advanced functionality in their bathroom.

The TOTO NEOREST NX1 smart toilet offers several features that align well with what buyers typically seek in a smart-toilet category. It includes an integrated bidet with front, rear, and soft wash modes, providing versatile cleaning options. The dual flush system with 1.0 and 0.8 gallons per flush options promotes water efficiency, and the Tornado Flush system is designed for powerful, thorough cleaning.

The ceramic surface is treated with CEFIONTECT glaze to help prevent waste buildup, which supports easier maintenance. The EWATER+® technology uses electrolyzed water to keep the bowl cleaner, contributing to hygiene. The seat is plastic, and given TOTO's reputation, the build quality is expected to be solid, though the product’s relatively high weight (141 pounds) means installation may require professional assistance.

This model is suitable for users seeking a reliable, water-efficient smart toilet with quality bidet functions and enhanced cleanliness but may not include some advanced automation and convenience features that other premium models offer.

The Bio Bidet BB2000 Bliss Electric Bidet Toilet Seat offers a range of high-end features that make it a strong candidate in the smart toilet category. One of its standout features is the adjustable stainless steel nozzle, which allows for personalized front and back washes, enhancing comfort and cleanliness. The bidet also provides unlimited warm water, adjustable temperature, and a built-in warm air dryer, which together significantly improve user convenience.

The heated seat with a sensor, slow-close lid, night light, and deodorizer add further luxury and comfort to your bathroom experience. The included wireless remote control makes operation straightforward and user-friendly. Another advantage is its easy installation process, which can be done without professional help, thanks to the included parts and instructions. It's designed to cater to a wide range of users, including seniors and those recovering from surgeries, by ensuring a hygienic and comfortable experience.

However, there are some considerations to keep in mind. The unit is relatively heavy, weighing over 15 pounds, which might be a factor during installation for some users. Additionally, it requires electricity to function, so an accessible power source is necessary. Despite these minor drawbacks, the Bio Bidet BB2000 is energy-efficient, consuming 1 gallon of water per minute and operating at a voltage of 120V. With a 3-year manufacturer warranty, this bidet seat is a reliable and luxurious option for anyone looking to upgrade their bathroom.
